Most of us probably know the feeling of both sweat and pleasure that comes from a good physical work out. But what you may not realize is that physical exertion is also making your brain happy- and healthier. New York University neuroscientist Wendy Suzuki has devoted her life’s work to understanding this connection between exercise and the mind, and she’s got some ideas about how to optimize your mood, memory, and mind with the right work out personalized for you. In fact, she’s even in the process of starting up a new company called BrainThrive to create exercise “prescriptions” that will allow you to determine when to exercise, how long to exercise and what are the best work out options for your unique situation. So, if you’re looking to protect your brain against such neurodegenerative diseases as Alzheimer’s, watch Dr. Suzuki explain her work in her recent TED talk Here and pick up a copy of her recent book Here.
